Objectives: This study aims to see the effect of red fruit oil (RFO) on glutathione peroxidase (GPx) level at maximum physical activity. Methods: This study is an experimental research using the design of randomized control group pretest-posttest. This study was using 24 male mice divided into four groups, the control group was given aquadest, the treatment groups P1, P2, and P3 were given the RFO orally of 0.15 ml/kg BW, 0.3 ml/kg BW, and 0.6 ml/kg BW, respectively, for a month. The level of GPx was checked for all groups at the beginning of study and after the maximum physical activity. The obtained data were then tested statistically using t-test and ANOVA. Results: The result shows the RFO supplementation during exercise increased the GPx level in P1, P2, and P3 groups with p<0.05, and the higher RFO dosage resulted in higher GPx level at p<0.05. Conclusion: The conclusion of this study is the RFO could increase the level of GPx at maximum physical activity. © 2018 The Authors.
